Acyclovir or Zovirax - which is better: reviews of patients and doctors

Acyclovir or Zovirax - which is better: reviews of patients and doctors

Doctors trust Zovirax more. But, nevertheless, they often prescribe Acyclovir, especially if the patient has herpes on the face, and the area of ​​eruptions is not too large. In such cases, the sores on the lips heal quickly - in a few days.

According to the majority of patients, Acyclovir and Zovirax act in the same way, there is no difference between them (except that the second deals a greater blow to the wallet). But still, Zovirax received a minimal advantage, as some people noticed that it helps better. Among the advantages of this particular drug, people attribute the fact that it has a thicker consistency, it is better kept on the lips (Acyclovir instantly melts). Zovirax, drying up, forms a crust on the bubbles. Under it, microbes die faster, since there is no access of oxygen and moisture.

Users indicate that it is better to use one and the other medicine at the first signs of the disease: then ointments help to get rid of the “cold” on the lips faster. Some people recommend taking a couple of pills of one or another medicine a month for prevention. Should I listen to this recommendation - you decide. But the drugs are toxic, do not forget about it!

Patients rarely mention side effects. Rather, they complain that the ointment had no effect. But this happens most often with large-scale lesions, long-term herpes infections, or if external antiviral drugs are used too often. In such situations, it is better to carry out therapy with pills or make injections of Zovirax. They will kill the virus inside the body.

So, what should be the conclusion that it is better - Acyclovir or Zovirax? If you trust domestic drugs, feel free to choose Acyclovir. If the herpes jumped on the lips or in the nose, then you should not spend large sums to purchase Zovirax. You can get along with Acyclovir - it will effectively stop the reproduction of the virus. But for the treatment of genital herpes or shingles depriving the best option is still Zovirax, because its effectiveness and harmlessness is higher.
